What is a Rising Stem Valve Used For?

Rising stem gate valves are commonly found in several systems. Thanks to their reliable performance and precise control of fluid flow, these valves can help produce smooth and efficient operation. 

How Does A Rising Stem Valve Work?

One of the best features of a rising stem valve is its straightforward operation. Add to this the fact that this class of gate valves offers reliable performance and precise control of fluid flow.

The valve comprises a gate (or wedge) and a stem that rises and falls. The mechanism controls the opening and closing of the valve. Once the valve is open, the stem visibly moves up. This indicates the valve’s position.

The rising and falling of the stem is particularly advantageous for operators. This is because they need to quickly verify whether the valve is open or closed.

The mechanism of the rising stem involves the rotation of the threaded stem. As the stem turns, it engages with the gate, moving it up and down. This linear motion allows the gate to either permit or obstruct fluid flow.

Purpose of A Rising Stem Valve

Rising stem valves serve numerous purposes. Some of them are the following:

Flow Control

This class of valves regulates the flow of liquids and gases through pipelines. Such a function leads to smooth and controlled operations.

Isolation

Rising stem valves isolate sections of a pipe. Through this purpose, operators can conduct proper maintenance and repairs without disrupting the entire system.

Pressure Management

Valves with rising stems help manage and control pressure within a particular system. Thus, they are preventing potential damage due to overpressure.

Industrial Applications of Rising Stem Gate Valves

Due to their uncomplicated design and robust construction, rising stem gate valves are used across various industries:

Water Treatment and Distribution

These valves are useful for regulating water flow in municipal systems and wastewater facilities. In the latter, rising stem valves control the flow of effluent through different treatment stages, ensuring efficient processing.

Oil and Gas Industry

Rising stem valves manage the flow of oil, gas, and other refined products. Their durability is useful in preventing leaks even in harsh conditions.

Within oil and gas refineries, these valves are used to control the flow of hydrocarbons. This function is needed for efficient refining processes.

Chemical Processing

Chemical plants use these valves to manage the flow of various chemicals, with the visible position indicator enhancing safety.

Power Generation

In this industry, cooling systems are necessary. A rising stem valve helps control the flow of cooling water, to ensure cooling performance. On the other hand, rising stem gate valves regulate steam flow in power generation systems, contributing to efficient and safe operations.
